Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Green beans
The main vegetable, which softens in the brine and vinegar and takes on the pickled flavor and color.
Coarse sea salt
Draws water out of the beans in the brine, firming their texture and seasoning them.
Vinegar
Its acidity preserves the beans and gives the pickle its sharp, tangy flavor.
Black pepper
Adds sharp, warm aroma and flavor to the pickled beans.
Mace
Adds a warm, aromatic spice flavor to the pickle.
Cloves
Adds a strong, warm aroma to the pickle.

The step that matters

Pour boiling hot vinegar over the beans. Hot vinegar penetrates the beans more readily and its acidity helps preserve them. The beans must stay fully covered by the liquid, since any exposed part can spoil or discolor.

Swap the green beans

How well each one fits the dish's main ingredients (vinegar, pepper, mace, clove):

  1. Capsicumfits better
  2. Carrotfits better
  3. Mustardfits better
  4. Green beansthe original

Fit is the average pairing score against vinegar, pepper, mace, clove. Candidates are from the same food group and used in at least 100 recipes.
